An investigator close to the case told ABC News that the warrant would be based on evidence that Hernandez’s home security system was destroyed. Sources also said that a cellphone used by Hernandez was handed over to investigators "in pieces'' by his attorneys.

According to ABC news, police want to know why a team of house cleaners were hired on Monday to clean Hernandez's million-dollar mansion.

Hernandez, 23, has not been named as a murder suspect, but a 2013 Chevrolet Suburban with Rhode Island license plate rented in his name has emerged as a key piece of evidence in the investigation.

Hernandez was seen arriving home late Friday afternoon with his attorney.

On Thursday, he was seen driving to Gillette Stadium. The Patriots public relations department told SportsCenter 5 there were no coaches on site at Gillette and Hernandez quickly left. He was then seen driving to a location in downtown Boston.

In an unrelated case Wednesday, a lawsuit was filed against Hernandez in the state of Florida.

The plaintiff's attorney, David Jaroslawicz, says Hernandez had a disagreement with a man in a Miami-area strip club. The two left the club together, and were traveling in a vehicle toward Palm Beach. The lawsuit claims Hernandez, allegedly in possession of a weapon, fired the gun in the direction of the victim, striking him in the face.

Hernandez, 23, was born in Bristol, Conn. The New England native played college football at the University of Florida from 2007 to 2009 and was drafted by the New England Patriots in the fourth round of the 2010 NFL draft.

In 2012, the Patriots signed Hernandez to a five-year extension, running through 2018, that included a $12.5 million signing bonus, the largest signing bonus ever given to an NFL tight end.
